Technology is revolutionizing education. Global networks, powerful personal computers, and user friendly, graphically oriented software are creating a new infrastructure that promotes rapid, efficient access to information. Images, text, audio, and video can be integrated into interactive multimedia presentations, providing a hierarchy of knowledge that can be traversed by the click of a mouse. The extensive use of images in our arena makes radiologic education a major beneficiary. Because the components (text, images) of educational presentations are stored electronically on a network rather than on the printed page, an individual component can be linked and bundled into as many different presentations as desired. Furthermore, components of information can exist on different computers throughout the world and yet be linked by software into a single presentation.
